i saw that documentary to. there was even one story about how this lady on a bike tour there was complaining to guides about her brakes. not taking her seriously, they rode on. a short time later, she lost control and plummeted off the cliff.
my mate has just returned from there as a mtb guide on that road and another company had some dude go off an 80ft cliff, my mates crew was called on to get him out coz they had the gear. he said it was pretty hard out.
"do a flip!"
